Fall 2003 Video Card Roundup Part I - ATI's Radeon 9800 XT

The Newcomers
As we briefly mentioned, there are three new products to talk about today – the Radeon 9800 XT, the Radeon 9600 XT and then NVIDIA’s NV38.
The XT line of Radeon 9x00 cards is specifically targeted at the very high end of the gaming market. With AMD and their Athlon 64 FX, Intel and the Pentium 4 Extreme Edition, it’s not too surprising to see even more companies going this direction. With an ultra-premium part like the Radeon 9800 XT the profit margins are high and more importantly, the PR opportunities are huge – claiming the title of world’s fastest desktop GPU never hurts.
The effort required to produce a part like the Radeon 9800 XT is much lower than a serious redesign. When making any kind of chip (CPU, GPU, chipset, etc…) the design team is usually given a cutoff point where they cannot make any more changes to the design, and that is the design that will go into production. However, it is very rare that manufacturers get things right on the first try. Process improvements and optimizing of critical paths within a microprocessor are both time intensive tasks that require a good deal of experience.
Once ATI’s engineers had more experience with the R350 core and more time with it they began to see where the limitations of the GPU’s clock speed existed; remember that your processor can only run as fast as its slowest speed path so it makes a great deal of sense to change the layout and optimize the use of transistors, etc… to speed up the slow paths within your GPU. This oversimplified process is what ATI and their foundry engineers have been working on and the results are encompassed in the R360 – the core of the Radeon 9800 XT.
The Radeon 9800 XT is able to run at a slightly higher core frequency of 412MHz, quite impressive for ATI’s 0.15-micron chip (yes, this is the same process that the original R300 was based on). Keep in mind that the Radeon 9800 Pro ran at 380MHz and you’ll see that this 8% increase in clock speed is beginning to reach the limits of what ATI can do at 0.15-micron.
The Radeon 9800 XT does receive a boost in memory speed as well, now boasting a 365MHz DDR memory clock (730MHz effective) – an increase of 7% over the original Radeon 9800 Pro and an increase of 4% over the 256MB 9800 Pro. ATI was much more proud of their core clock improvements as we will begin to crave faster GPU speeds once more shader intensive games come out.
The Radeon 9800 XT does have a thermal diode (mounted on-package but not on-die) that has a driver interface that will allow the card to automatically increase its core speed if the thermal conditions are suitable. The GPU will never drop below its advertised 412MHz clock speed, but it can reach speeds of up to 440MHz as far as we know. The important thing to note here is that ATI fully warrantees this overclocking support, an interesting move indeed. Obviously they only guarantee the overclock when it is performed automatically in the drivers, as they do not rate the chips for running at the overclocked speed in all conditions.
The OverDrive feature, as ATI likes to call it, will be enabled through the Catalyst 3.8 drivers and we’ll be sure to look into its functionality once the final drivers are made available.
The Radeon 9800 XT will be available in the next month or so and it will be sold in 256MB configurations at a price of $499 – most likely taking the place of the Radeon 9800 Pro 256MB.

#22,/me waves.
Thanks for the personal attack though. I admit to not knowing every last detail about 3D that there is to know, but some things don't take an EE degree to figure out.
If you want to see my detailed reasons for not liking this review and its conclusion, read the following url:

#73 makes a good point...but at the same time I've made a few observations on that note. I've seen a lot more motherboards with a gap between the AGP slot and PCI slots...and while some people would be led to believe it is just for Nvidia cards, this is most likely not the case. Graphics cards in general put out a lot of heat, and it's never a good idea to put a big card right next to your graphics card anyway, you're just begging for heat problems. For the most part it's just the Nvidia reference design that takes up two slots. The boards distributors usually use their own cooling anyway and plenty are available that only use one slot.What it all boils down to is that it's not the size it's how you use it. :)
Now as far as ON topic ;) I thought the benchmarks did what they should....they showed performance in today's popular games and some signs of what is to come. For those of you crying because there are no significant DX9 entries...guesss what...DX9 games aren't available in any kind of quantity and won't be any time soon. Granted there will be some, but the bulk of games that are released in the next 6 months will be built on DX8 with some DX9 features. By the time the publishers start churning out DX9 titles guess what...the new chips will be ready for release which will run full DX9 titles better.
Coincidence? Not at all. Does Nvidia or ATI want you to buy their 500 dollar card now and use it for the next two years...hell no. They want you to buy bleeding edge technology for now, then buy another new one in a year or less...and so on and so forth. There's a reason they release a whole line of cards at once (performance, mainstream, budget), that's so they can tackle the whole market with each release. If they make a card too good now you won't need to buy their next one...welcome to the world of trying to make money :).
Ok I'll stop rambling...good job with benchies Anand :)

Please add a benchmark for MMORPGs of some sort to your suite (Dark Age of Camelot, Everquest, etc.)sorren - Wednesday, October 1, 2003 - link
For those of us with 17"+ LCD Monitors, the 1280x1024 resolution results would be more useful since this is the most common native resolution for these monitors. The games look great, just as long as we keep some games other than just action and FPS games. I mostly play strategy and RPGs so it's good to see Warcraft and NWN on the list. Keep up the great work!Anonymous User - Wednesday, October 1, 2003 - link
my guess is that because of the massive # of games that they were using for benchmarks...they didnt have time to test in more resolutions?also #42 makes a lot of good points.

to question 75:If thats the case why dident they test the cards at 1280X1024 for this PRELIMINARY review as they do with all other high performance cards, seems sort of odd to me.

Just a friendly reminder:NV38 is still not a 'finished' design; and by finished I mean there is still not a publicly available set of drivers supporting the card. The card itself is not even publicly available much less on the OEM market, therefore it makes it rather difficult to fully benchmark this product. Likewise, to a certain extent the 9800XT is not a finished design even though it's on the market, as the Overdrive (ATI supported overclockin) feature is unavailable until the Catalyst 3.8 drivers become publicly available in the next week or so.
The point of this rant is that the information presented here in Anandtech's review is PRELIMINARY. Regardless of Anantech having engineering samples or final products, beta drivers or publicly available drivers, they can only work with what they have available to them at the present time, and when reading this review you HAVE to take that sort of non-explicitly-stated information into context to guage credibility.
Personally, I believe that given what is available at the present time Anandtech has done a very good job of providing a sample guage of what to expect from the newest 'refresh' video cards which are still incomplete in regards to being able to be all that they can be (special application optimizations not withstanding of course). While I would like to see them guage these cards against older cards as someone mentioned earlier in this thread to see if upgrading is worth it, I don't see the point of doing so until these products are fully completed (i.e.: they're readily available in stores and they have publicly available drivers).
So perhaps after the NV38 truly comes to market that would be a better time to insist on seeing an all-out battle of the GPU's. Just my two cents on the matter, have a good day.

I would like to see Battlefield 1942 addedAnonymous User - Wednesday, October 1, 2003 - link
when is nvidia ganna work on making the card smaller so it doesnt take up a good pci slot
